Kidney stones are small, hard mineral deposits that form inside your kidneys. The stones are made of mineral and acid salts.
Pain from kidney stones is usually of sudden onset, very severe and intermittent, and not improved by changes in position, and it radiates from the back, down the flank, and into the groin. Nausea and vomiting are common.
Preventing kidney stones means preventing the conditions that support their formation.
Here are the top 5 kidney stone prevention tips
Limit animal protein
Eating too much animal protein, such as red meat, poultry, eggs, and seafood, boosts the level of uric acid and could lead to kidney stones.
A high-protein diet also reduces levels of citrate, the chemical in urine that helps prevent stones from forming.
Calcium is not the enemy
Calcium in food doesn’t have an effect on your risk of kidney stones. Continue eating calcium-rich foods unless your doctor advises otherwise.
Drinking enough water each day is the best way to help prevent most types of kidney stones. Health care providers recommend that a person drink 2 to 3 liters of water a day.
Though water is best, other fluids may also help prevent kidney stones, such as citrus drinks.
A high-sodium diet can trigger kidney stones because it increases the amount of calcium in your urine. So a low-sodium diet is recommended for the stone prone. Consider using a salt substitute.
Eat fewer oxalate-rich foods
If you tend to form calcium oxalate stones, your doctor may recommend restricting foods rich in oxalates. These include rhubarb, beets, spinach, okra, Swiss chard, sweet potatoes, nuts, tea, chocolate and soy products.
